Oi chopinhead, seja bem vindo ao fórum!
Sim, é possível ter iterates dentro de outros, eu mesmo já usei 3 níveis de iterate. Vc pode postar o trecho do .jsp aqui?, fica mais fácil de ajudar.
abraços,

Tentei tb retirar toda a logica de dentro dos iterates deixando eles vazios e mesmo assim acontece a mesma coisa. Os espaços em branco gerado no html causa o erro java heap space.
Valeu por ter respondido.
